9 Chrome Extensions That Every Web Developer Should Use

Mark Vassilevskiy — Sat, 20 Nov 2021 00:23:39 +0000

Chrome is the most famous browser in our world and of course, it has many extensions which you can easily download into your browser and use. Some of them are just for your better productivity and for better using your browser, and some of them are really useful for every web developer because they have amazing features that simplify the web layout process a hundred times. I tried to find the best of the best among countless extensions and to show these 8

1. WhatFont

the easiest way to find fonts on a website is WhatFont. Everything that you need is to click on what font extension icon and start to move your cursor through the whole website and when you will be hovering on the text he will show what font that is

2. ColorZilla

one of the most popular Chrome, Firefox Extension is ColorZilla and it uses to pick the color from a webpage. It actually has the same mechanics as the earlier extension, click at the ColorZilla extension button and then choose "Pick Color From Page" and aim at the color that you want to copy. It's fast, simple, and efficient

3. Window Resizer

To please all users you should make a website that will look good on all screens regardless of size
Window Resizer is as you may have noticed extension that uses to change your standard web browser screen to maybe iPhone 6 or Laptop. It's useful for adaptive web layout

4. PerfectPixel

PerfectPixel is the extension that helps you to develop your website with pixel-perfect accuracy. You can add your own project and it will make a second layer over the main website itself. Because of this, you can make your website better and better

5. Page Ruler Redux

If you want to measure the size of a block on a website it can be really awful, without Page Ruler Redux extension of course, because it helps you easily measure everything you want to, just hovers the measuring tool on the area and then drag

6. Loom

Sometimes just to do screenshots isn't enough and Loom with help you with it. It's actually a video recorder in your browser with
which you can record any animations, bugs, or whatever you want
I use this extension myself and just don't know how to do a joint project without this incredible extension

7. Svg-grabber

Once in a while, you see an SVG icon at someone else website or just deleted a file from your computer and wanna copy this. Svg-Grabber can show you every SVG icon that was used on this webpage and you can easily download them all

8. Momentum

Do you remember these ugly default Chrome's New Tabs? Momentum will replace them with the most beautiful photos and inspiration phrases, also it has a small to-do list and you can connect your account with it (Todoist, etc.)

9. The Greatest Suspender

If you have a slow laptop or computer then The Greatest Suspender is a must-have for you, when you afk or didn't use one of your tabs it will automatically suspend it and chrome will no longer have as much RAM as before. It has Light and Dark mode

Conclusion

These were, in my opinion, the best Chrome extensions that every Web Developer should try. I hope that you enjoyed this article.

How To Learn Better And Avoid Procrastination

Mark Vassilevskiy — Fri, 19 Nov 2021 16:18:30 +0000

In this article, I will tell you why Switching modes of thinking is one of the most important parts of learning, why sometimes you shouldn't chase those who have already achieved success in this area (Math, Physics, Programming, and whatever else you want), What is the "Einstellung Effect", misunderstanding and making mistakes are common things, we will be fighting with your Procrastination (when it is needed) and many other really useful outputs

Focused and Diffused Modes of Thinking

The ability to Switch Attention - first to grasp the detail of the general picture being studied, and then return to the subject

Focused - mode is very important and useful for learning, it assumes direct access to the problem being solved and uses a rational, consistent, and analytical approach.

Diffused - mode is essential for learning too. It allows you to experience sudden insights and find unexpected solutions.

With focused thinking, you sometimes can find yourself focusing deeply on a problem and trying to solve it in the wrong way. And with absent-minded thinking, does not allow you to clearly focus, but it allows you to get closer to the solution. The difference between them can also be explained with the help of a flashlight, which has two modes: focused and diffuse. If you are trying to understand or learn something new, then it is better to turn off precise focused thinking and turn on diffuse mode, which allows us to see the big picture. to switch from one mode to another, you need to distract yourself, for example: take a walk, do a few push-ups, eat, talk to someone or even play video games with your friends

What is the "Einstellung Effect" and How to Get Rid of It

"Einstellung Effect" - this is when the failure in the assimilation of new concepts and solving problems is due to our fixation on the wrong approach

Its essence is that sometimes it is difficult even to determine from which side to approach a decision. One of the common mistakes when studying math and science is that people jump into the water before they can learn to swim. In other words, they start working on the problem without reading the textbook. To remove that barrier we should switch our thinking as we said earlier. Remember that flexibility is your helper

The more you try to tune your brain to creativity, the less creative your ideas will be. Relaxation is an important part of hard work

Confusion and Misunderstanding is a Common Reaction

Misunderstanding is a useful part of the learning process; as soon as a student meets a dead end, he immediately gives up. It is even more difficult for excellent students in this because study has always been easy for them and they do not even realize that the feeling of misunderstanding and deadlock is a standard part of the process. Learning is overcoming mistakes. Asking the right question - 80% success

"I have not failed. I've just found 10,000 ways that won't work" - Thomas Edison

How to Avoid Procrastination

Procrastination is not uncommon. If you postpone classes until later, you leave yourself time only for the superficial study of the material in a focused mode

If procrastination is your weakness, try to remove any noises and just sit for 25 minutes, concentrating on the task, but not thinking about the solution itself, but thinking about finding these solutions, and then reward yourself by surfing the Internet for aphids. You will be surprised at how effective it is. Will you get results if you postpone your training for an essential race until the last day? So it is with mathematics and natural sciences. The habit of procrastination affects all aspects of life negatively and when you remove it you will notice Improvement everywhere

Why Is Sleep So Important?

it can be compared to a rest stop during mountain climbing, in other words, if you are in an absent-minded state, this does not mean that you can wander around and wait for you to come somewhere, but just restore strength. Also, it flushes out toxins and deepens neural connections. If you repeat the material fractured by sleep, then in a dream the brain will abundantly chop it

Don't try to keep up with the excellent students

There are "Working" and "Long-Term" Memory

"Working" - which is working at the moment. It can store up to 4 objects on which you need to keep attention, otherwise, the information will be forgotten, you should not hammer it over trifles. Long-term memory as a warehouse. It is capable of accommodating billions of objects, many of which will remain buried. To move information from work to long-term, spaced repetition will help us. It is better to repeat the material several times a week than to repeat it 20 times in one day

Ideal Memory Isn't the Better Way

Focused thinking plus repetition gives an imprint on the memory. And if you have a phenomenal memory, then each memory imprint will be emotional and colorful, it will be difficult for you to compose an understandable portion for assimilation. In other words, you will not see the whole forest, because every tree will be alive for

The illusion of competence - when a solution has already been given and the student glances over it, saying that he understood the material

Conceptual Portions

It's one of the main things of learning, there are 3 steps how to format it:

The first step - chunking is to just focus on the information
The second - to understand the main idea
The third - to accumulate context so that you know not only how to apply this information, but also where you can use it
The fourth - practice periodically, nothing can be learned without a good practice

As Alan Baddeley said, the intention to learn only helps with the right learning strategy Knowing about gaps is the first step in closing them

The illusion of competence - when a solution has already been given and the student glances over it, saying that he understood the material

Why Is "Interlining" So Important For Further Training

Practicing only one problem-solving sport, will bring you to automatism, and in the subsequent time it will be useless to waste time on it, for this, you need to combine different approaches. You must understand that the ability to use a particular method is only part of the success, you need to know when to apply it.

How to Change Habits

Signal. Find out why you are procrastinating. In the case of procrastination, this is an automatic habit and you don't even notice when you start scrolling through the feed-in social networks. It is useful to introduce new signals, for example, do homework right after school. Pierce Steele notes "if you protect your daily routine, it starts to protect you."
The sequence of actions. The key to change is planning and developing a new ritual. The Tomato Method - This can be especially useful when you are training a new response to signals. Difficult classes should not start on an empty stomach
Reward. Can you win a bet with yourself? Spend the whole evening watching TV without remorse or guilt?
Faith. Faith in your strength is needed. Overcoming the cravings for old, comfortable habits can be done by believing in a new approach. One of the most effective methods is mental comparisons when you compose the current state of affairs with which you want to achieve

Conclusion

I hope that you enjoyed this article. These are some of the most useful tips for better learning that will help you. Don't forget about like :)

13 Sublime Text Plugins that Every Developer Must Use

Mark Vassilevskiy — Fri, 19 Nov 2021 15:39:17 +0000

Sublime Text 3 is one of the most popular free IDEs for writing your code. You can use it for opening files (.txt and more), as well as for small projects that use Python and Web-dev. Earlier, I had written an article about VSCode Extensions. However, if you prefer to use Sublime Text 3 rather than VSCode, then this compilation of the 13 plugins is exactly for you.
I think these are the most common and the greatest Sublime Text 3 plugins that every developer (doesn't matter who are you - full-stack developer or data scientist) should work with.

1. Package Control

When you just install Sublime Text 3, you should immediately install the Package Control plugin. It is the most basic plugin that will allow you to install, delete, redact other plugins easily and without any problems. As I said earlier, after installing this plugin you don't have to do this anymore.
Use command ctrl+shift+p (for Windows or Linux) or cmd+shift+p (For Mac).
Type "Install-Package Control" and press enter.

2. Emmet

This plugin is second in popularity and one of the most useful. Emmet helps you to write a lot less. It lets you use abbreviations that automatically deflate into fully functional code.
You will need to use Package Control as we mentioned earlier. Write "Install-Package Control" again and then write "Emmet" and press enter.

3. Alignment

Alignment is a useful tool for aligning multiple sections or multi-line sections, which means you can align multiple selections, or lines, via delimiter such as =. Simply type ctrl + alt + a on Windows, or cmd + ctrl + a on a Mac. And again use "Install-Package Control" command to install it.

4. Git

This plugin brings Git into Sublime Text 3, so you don't need to go back and forth between the command line and your text editor. To get started quickly, install the plugin and use the Command Palette to launch your Git commands

5. JSHint

JSHint is a really good plugin without which I can't normally write JavaScript code. As you might have noticed it helps with your JavaScript code, specifically it shows where you made an error and also proposes to you how to fix it.

6. ColorPicker

ColorPicker a really good plugin for Sublime Text 3 because it adds a color panel to your CSS code. To open the color picker, simply type cmd+shift+c on a Mac, or ctrl+shift+c on Windows or Linux.

7. Terminal

The Terminal plugin lets you open your project folders in the terminal directly from Sublime Text 3 - with a hotkey. It is a very helpful plugin when you need to execute command lines inside the given folder.

8. BracketHighlighter

When you work with many count of brackets it's very difficult and painful to find the right brackets. BracketHighlighter underscores and highlights all brackets.
BracketHighlighter matches a variety of brackets such as: [], (), {}, "", '', , and even custom brackets.

9. LiveReload

A small but necessary plugin for most web developers is LiveReload. Instead of having to refresh your browser every time you make a tiny change to a file in order to see results, LiveReload will simply sync with your browser of choice and instantly display the updated results.

10. AutoFileName

The AutoFileName plugin completes filenames automatically. It triggers a dropdown with file names relative to your existing file and the subsequent path as you type. For example, when you want to write something for the url attribute in your HTML tag, it will propose the name of the file in your folder.

11. SideBarEnhancements

The SideBarEnhancements plugin adds a new window to your Sublime Text 3 where you can easily manage your folders. Also, it provides delete options such as "Move to trash", includes an "Open with…", gives you the ability to move files and more.

12. A File Icon

This plugin is great for easily scanning what files you have in your project. It simply adds pretty and customizable icons to supported files in your project sidebar.

13. Theme - One Dark

And the last plugin for today is "One Dark", which is a theme for Sublime Text. This plugin doesn't have any functionality but adds a really beautiful interface with which you can code in a prettier environment.

Conclusion

These were the most common and useful plugins for Sublime Text 3 - one of the most popular IDEs. I hope you enjoyed this article. Let me know in the comments if you want more articles like this.

Python features you'll want to repeat

Vadim Kolobanov — Tue, 16 Nov 2021 15:07:37 +0000

File server on a computer with mobile access

You can access your file system by running a file server on your computer. Navigate to the desired directory that you want to access and run the following command:

# python version >=  3.X
python -m http.server
# python version >=  3.X
python3 -m http.server #for Linux

# If Python version >= 2.X and < 3.X
python -m SimpleHTTPServer
#default port: 8000

This command starts a file server that can be accessed on the same network. To access your files on a mobile device, simply connect to the same network (Wi-Fi or use the phone's access point on a laptop). Now open the browser in your phone.

<your-computer-ip>:port

Check your IP by running - ifconfig. Check your local IP

Example:

192.168.43.155:8000
And on the mobile phone, you will see the current directory

Convert CSV to JSON 1 line

If you're a programmer, you'll probably be lazy and want to automate pretty much everything you can, right?

Don't worry, the python will cover you. There are a lot of things that you can automate in just 4-5 lines of code. From installing cron jobs and reminders to uploading your favorite YouTube videos, you can do it all with a few lines in python.

Example - convert CSV to JSON
You can convert a CSV file to JSON with just one command in Python!

python -c "import csv,json;print json.dumps(list(csv.reader(open('your_csv_file.csv'))))"

Replace it with anyfile.csv and you will get JSON output!

Easy, right?

Comics

Yes, these are comics in python!


 import antigravity

Will they add brackets in python?


from __future__ import braces
  File "<stdin>", line 1
SyntaxError: not a chance

A simple life lesson


>>> import this
>>> love = this
>>> this is love
True
>>> love is True
False
>>> love is False
False
>>> love is not True or False
True
>>> love is not True or False; love is love  
True

Soft skills that will improve your work and life. With self-check

Vadim Kolobanov — Mon, 15 Nov 2021 20:38:08 +0000

Being a programmer in 2021 is not the same as ten years ago. The world is constantly changing, and many of the skills that were important back then have faded into the background over time. And what skills should a developer have in order to remain a sought-after specialist, for example, in five years? If you don't have them, maybe you should think about their development now?

In this post, I want to talk about skills that will help you stay in demand as a developer even in conditions of constant change. Usually, IT specialists rely on the scientific and technical base, which is important for understanding the functioning of the system as a whole. This includes knowledge of the operating principles of the OS, the network stack, databases, and the mathematical apparatus that underlies any algorithm or protocol, etc. However, hard skills alone are not enough — communication skills, the ability to build a workflow with a team and/or strangers, flexibility in decision-making, and other soft skills are also needed. Moreover, it is important not just to have the — soft skills that should be integrated into the overall development process and go in close conjunction with professional skills. Seven of them will be discussed today.

1. Comprehensive problem solving

The demand for specialists who are able to approach the task from different sides is steadily growing. Most people cannot solve complex problems because they often use technologies aimed at the process, not the result. A developer using an integrated approach can not only identify the problem, but also determine its causes, and most importantly, "calculate" further steps.

Self-test:

Colleagues complain about a recurring problem. If it arose in your team, where would you start solving it?
Do you calculate the possible risks when choosing a certain solution?
How to understand that you are really solving the problem, and not eliminating its "symptoms"?

2. The ability to convince

The ability to convince — that is, to present your idea, make arguments and tell a story so that listeners are passionate - is necessary not only for those who constantly communicate with clients. This skill will help to defend your point of view, inspire like-minded people. And in order for colleagues to listen to you not out of politeness, but attentively and intently, it is highly desirable to make your story not only convincing but also interesting.

For example: when preparing a presentation about a release, you try not to load your colleagues with a dry list of facts with technical details, but build a story: add explanations, vivid examples, think about how you will manage the attention of listeners, and prepare arguments for answers to possible questions.

Self-test:

Have you noticed that you are interrupted at meetings? Was there a feeling that no one was listening to you?
Do you try to give illustrative cases when defending your point of view?
How will you start the story about yourself? Rehearse a small speech.
Remember the case when, after a conversation with you, a colleague changed his mind. What exactly helped you convince him?
How do you respond to objections?

3. Cooperation and teamwork skills

I think many will agree that the community plays a significant role in the IT environment: experienced developers help colleagues and willingly share their experiences. Nevertheless, there is a stereotype that it is normal for a programmer to be closed, but it is difficult to interact with a closed person since he almost never offers ideas and is not inclined to discuss current processes. Therefore, more and more companies are paying attention to whether a specialist is able to work in a team, whether he understands colleagues as well as the project itself, whether he is able to give and receive feedback.

Self-test:

You need to talk to a colleague you didn't know before. Where will you start?
One of the team members repeatedly passes the work with errors. What will you do?
What words will you choose to make the criticism sound friendly?
Do you celebrate the successes of your colleagues and talk about them publicly?
What helps you feel the mood of the interlocutor and tune in to his wave?

4. Ability to plan your work

Employers value specialists who are able to plan, give accurate estimates of the complexity of tasks and adhere to deadlines regardless of the language, technologies, and methodologies used.

Example: to organize the work of a group (if you are a leader) or your own, you plan sprints, make sure that there is a time interval between the task and the solution, which will allow you to organize things and prioritize. During the day, you stick to what you have planned and do not get distracted by other requests so that the work becomes more calm and predictable.

Self-test:

You are asked to name the deadlines for the project's readiness. What will guide you in the assessment?
It's the middle of the working day, and suddenly a colleague sends you a link. You know that there is a useful and important article there. What will you do?
Do you make work and personal plans for the day/week/month? How many of them can be completed?
Are you familiar with the Eisenhower matrix time planning method?
Do you know how much time it takes you on average for each type of task?
How many minutes/hours a day do you spend on social media? Do you track these statistics in any way? Do you use time trackers?
Do you practice taking a break from social networks and the Internet, digital detox?

5. Critical thinking

The ability to think critically is one of the key skills in our time. In a world where knowledge is power and the flow of information increases exponentially, you need to be able to ask questions, compare data and be critical of what others write. If we talk about professional development, critical thinking allows you to determine which set of skills you need. Someone needs clean code, knowledge of the version control system, and system thinking to work, and someone who is engaged in high-tech projects needs deep immersion in special sections of mathematics or physics.

Self-test:

Do you think when reading materials on the Internet about who publishes them and for what purpose?
How do you determine which information can be trusted? What criteria do you rely on when choosing information sources?
Do you check website addresses and connection security when clicking on unfamiliar links?
Do you have a list of trusted sources of information?

6. Continuous learning — long life learning

Many leading companies seek to hire full-stack developers who work freely with different technologies and platforms. Such specialists understand the principles of any development, starting from the network core level and ending with the interface level. This is impossible to achieve if you do not make it a rule to constantly learn new things. A sought-after developer is determined not only by the possession of a rare stack but also by the ability to easily "switch" between different languages and the desire to learn new tools every day.For example: although Java and C# have occupied a significant part of the market for several years, IT companies are increasingly using newer technologies (Kotlin, Swift, etc.). And, logically, developers who are proficient in several languages will give odds to those who are familiar with one or two technologies. In five years, new stacks will surely appear, so to remain in demand, it is important to constantly learn and be able to choose the right tool for solving a specific task, based on a comprehensive analysis of factors.

Self-test:

Do you participate in the development of open-source projects? How many commits have you made over the past year? How many bugs and suggestions have you created in the tracker? How many questions were answered?
How long have you been studying an unfamiliar technology for yourself?
What would you do if you found out about the emergence of a new language that is gaining popularity?
How do you react if you are offered to go to a training event?
What professional conferences do you attend?
What have you learned in your professional field over the past six months?

7. Compliance with work-life balance

Compliance with work-life balance and your well-being directly affect productivity: those who take care of themselves usually live longer, work more efficiently and have time to pay due attention to other important matters. The topic of health is closely connected with all spheres of life, including work. I won't say anything about biohacking and implanting chips under the skin (this is the topic of a separate post — or even more than one), this item is more about attention to the body, to the psycho-emotional state, and also that the separation of personal and professional life helps them mutually support each other. Try to be more tolerant of others, especially if their point of view contradicts yours, express feelings without harming others, and be aware of what you can influence and what you can't. Find a hobby to your liking and remember that your career success will partly depend on how your life is organized after work and study.

For example: in order to feel cheerful and have more time, you go to bed on time, do not use the phone two hours before bedtime and do not grab it first thing in the morning, do not overeat. Thanks to this, you stay attentive and energetic longer.

Self-test:

When was the last time you underwent a comprehensive examination?
What do you do to ensure that your diet is balanced?
How many hours a day do you sleep? Do you get enough sleep? If not, what can you do now to improve the quality of your sleep? In the morning you feel cold, but you need to go to work. What will you do?
Do you work on vacation? Do you finish projects on weekends? Do you write to work chats in the evenings?
What are your hobbies? Have you been interested in something new for yourself for a long time?

This skill set does not appear with birth and is not strictly mandatory. But the development of these skills will not only give you success in work or in a team but will also make your life much better.

Instructive Python code examples for Beginners

Vadim Kolobanov — Wed, 10 Nov 2021 20:09:30 +0000

Photo by Pakata Goh on Unsplash

Hi guys! I want to show you beautiful and instructive python code examples. Using them in training, you will discover new language features and your code will look more professional.
Let's get started!

1. We get vowels

This example returns the found vowels "a e i o u" in the string. This can be useful when searching for or detecting vowels.

def get_vowels(String):
    return [each for each in String if each in "aeiou"]
get_vowels("animal") # [a, i, a]
get_vowels("sky") # []
get_vowels("football") # [o, o, a]

2. The first letter in uppercase

This works with a string of one or more characters and will be useful when analyzing text or writing data to a file. You can refine this code and make all letters uppercase to use case-independent search.

def capitalize(String):
    return String.title()
capitalize("shop") # [Shop]
capitalize("python programming") # [Python Programming]
capitalize("how are you!") # [How Are You!]

3. Print the line N times

Loops are a hard part of the language. You don't have to use them to output strings.

Look how it's easy

n=5
string="Hello World "
print(string * n)  #Hello World Hello World Hello World Hello World Hello World

4. Combine two dictionaries

Many of you guys, in order to combine 2 sequences, start overwriting one into the other. And again cycles, conditions, append and other horror... Catch a life hack, and please learn correctly!

def merge(dic1,dic2):
    return {**dic1,**dic2}
dic1={1:"Hello", 2:"Dev"}
dic2={2:"Python", 4:"Programming"}
# In these examples, Python merges dictionary keys
# in the order listed in the expression, overwriting 
# duplicates from left to right.
merge(dic1,dic2) # {1: 'Hello', 2: 'Dev', 3: 'Python', 4: 'Programming'}

5. Calculate the execution time

This example is useful when you need to know how long it takes to execute a program or function.

import time
start_time= time.time()
def fun():
    a=2
    b=3
    c=a+b
fun()
end_time= time.time()
timetaken = end_time - start_time
print("Your program takes: ", timetaken) # 0.0345
# I love you Dev =)

6. Exchange of values between variables

Learn to use fewer variables guys. This option will look more elegant

a=3
b=4
a, b = b, a
print(a, b) # a= 4, b =3

7. Checking duplicates

Here I draw attention once again to the fact that set contains immutable data. Just remember this

def check_duplicate(lst):
    return len(lst) != len(set(lst))
check_duplicate([1,2,3,4,5,4,6]) # True
check_duplicate([1,2,3]) # False
check_duplicate([1,2,3,4,9]) # False

8. Filtering False values (or other)

An easy way to remove values from the list. Beautiful, elegant, and will show your code as the work of a professional.


def Filtering(lst):
    return list(filter(None,lst))
lst=[None,1,3,0,"",5,7]
Filtering(lst) #[1, 3, 5, 7]

9. Size in bytes

This example returns the length of a string in bytes, which is convenient when you need to know the size of a string variable.


def ByteSize(string):
    return len(string.encode("utf8"))
ByteSize("Python") #6
ByteSize("Data") #4

10. Load memory

It will be useful if you want to keep track of the memory that your variables occupy. The main thing is to remember:
Simple is better than complex.
Complex is better than complicated.


import sys
var1="Python"
var2=100
var3=True
print(sys.getsizeof(var1)) #55
print(sys.getsizeof(var2)) #28
print(sys.getsizeof(var3)) #28

does not work with a recursive function

11. Anagrams

This code is useful for finding Anagrams. An anagram is a word obtained by rearranging the letters of another word.


from collections import Counter
def anagrams(str1, str2):
    return Counter(str1) == Counter(str2)
anagrams("abc1", "1bac") # True

12. Sorting the list

This example sorts the list. Sorting is a frequently used task that can be implemented with many lines of code with a loop, but you can speed up your work using the built-in sorting method. Study Python deeper! And you will be happy.


my_list = ["leaf", "cherry", "fish"]
my_list1 = ["D","C","B","A"]
my_list2 = [1,2,3,4,5]

my_list.sort() # ['cherry', 'fish', 'leaf']
my_list1.sort() # ['A', 'B', 'C', 'D']
print(sorted(my_list2, reverse=True)) # [5, 4, 3, 2, 1]

13. Converting a comma-separated list to a string

This code converts a comma-separated list into a single string. It is very convenient to list all the values of the list in one line. And besides, JOIN is a useful method in python

my_list1=["Python","JavaScript","C++"]
my_list2=["Java", "Flutter", "Swift"]
#example 1
"My favourite Programming Languages are" , ", ".join(my_list1))
#My favourite Programming Languages are Python, JavaScript, C++
print(", ".join(my_list2))  # Java, Flutter, Swift

14. Shuffling the list

Everything is clear from the name here. But you didn't know that, did you? Really?

from random import shuffle
my_list1=[1,2,3,4,5,6]
my_list2=["A","B","C","D"]
shuffle(my_list1) # [4, 6, 1, 3, 2, 5]
shuffle(my_list2) # ['A', 'D', 'B', 'C']

15 Splitting into fragments

This example will show how to split the list into fragments and divide it into smaller parts. Not so useful, but interesting


def chunk(my_list, size):
    return [my_list[i:i+size] for i in range(0,len(my_list), size)]
my_list = [1, 2, 3, 4, 5, 6]
chunk(my_list, 2) # [[1, 2], [3, 4], [5, 6]]

Tips for beginner programmers from a professional

Vadim Kolobanov — Tue, 09 Nov 2021 18:09:20 +0000

Hello everyone, I have accumulated in my observations a lot of useful tips on how to start learning programming, how to move on. I will tell you from my experience what you can do and what you can't do. How and where to go next if you get bored or you just get lost. I am sure that each of them will help both beginners and confident programmers. You will still get this experience, I'm just giving you a chance to do it earlier and not on your mistakes.

Don't learn programming on other people's projects by video. This is a very bad approach. A person who shows his own development may not know the right solution and teach it to others, and you will not even know about it, because you will remember the wrong approach.

Do not try to create your own project that you came up with during the training. You will learn only what is useful to you for it, but you will know programming very narrowly. I advise you to learn the language using simple mathematical examples or problems. You can find good practice and elegant solutions on sites like Hackerrank or CodeWars. Their people arrange puzzles according to difficulty levels, and if you have solved them (or not), you can see what the most optimal solution will be. It helps to learn how to act effectively and solve other people's problems, and in the comments, you will see a lot of ingenious solutions.

Try to learn consistently. Even if you are not interested in some topic in the language - force yourself to understand it. not to learn by heart, but to understand what its idea is, what is the meaning of this functionality

Pay more attention to books, not articles or videos. In the books, all explanations are structured and go sequentially. Otherwise, you will just learn pieces of the same pie, after a week you will not be able to reproduce it.

Try to reproduce any new function or information in the code yourself. Do it yourself, what have you learned. You've learned the list - make it up, play with it. Come up with a simple idea of where to use it.

Do not burn out. If you get bored, just switch to another idea, but be sure to come back in a few days. It helps.

Communicate with the community. Look for people with common interests. Alone you may never find out what other people know

Don't close in one language guys! Try to look around your tongue. Often people find themselves not in what they started to learn. They find their interest in what they stumbled upon in the process of the main study. A good programmer knows several languages or technologies.

Do not follow someone's training on the heels. When learning something new, try to use this information yourself and not rewrite the example from the video.

Don't learn to program for the money. Programming is your hobby, it's your entertainment, your favorite activity in the evening after work. Money should be a reward for effort, not the result of work.

Don't be afraid to offer yourself in other people's ideas and projects. If you already know the basics of programming well but are in doubt, remember - on the other hand, the same as you. He is strong in one thing, but maybe he is weak to your strong side. You will never know how strong you are if you are not appreciated by others.

Look for a way to motivate yourself! If you feel that you have lost interest - start a new project, come up with an interesting idea, write an article about your skills. Try yourself in Freelancing. Don't be afraid to screw up. You won't get anything if you don't do anything. Close your eyes and break into this world of programming with a run if you're scared)

Put on Heart if you liked it and you learned something new!
